Battle Abbey was built on the site of the battle. A plaque marks the place where Harold is believed to have fallen and the location where the high altar of the church once stood. The settlement of Battle, East Sussex, grew up around the abbey and is now a small market town.

The Bayeux Tapestry depicts the events before, during, and after the Battle of Hastings.

The Battle of Hastings is an excellent example of the application of the theory of combined arms. The Norman bowmen, cavalry and infantry cooperated together to deny the English the initiative, and gave the homogeneous English army few tactical options except defence.

Nevertheless, it is quite likely that this tactical sophistication existed primarily in the minds of the Norman chroniclers. The account of the battle given in the earliest source, the Carmen de Hastingae Proelio, is one where the Norman advance surprises the English, who manage to gain the top of Senlac Hill before the Normans. The Norman light infantry is sent in while the English are forming their shield wall (to no avail) and then the main force was sent in (no distinction being made between infantry and cavalry).

Succeeding sources include (in chronological order) William of Poitiers's Gesta Guillelmi (written between 1071 and 1077), The Bayeux Tapestry (created between 1070 and 1077), and the much later Chronicle of Battle Abbey, the chronicles written by William of Malmesbury, Florence of Worcester, and Eadmer's Historia Novorum in Anglia embellishes the story further, with the final result being a William whose tactical genius was at a high level—a level that he failed to display in any other battle.

The Battle of Hastings also had a tremendous influence on the English language, introducing many French words that started in the nobility and eventually became part of the English language itself.

As Paul K. Davis writes, "William’s victory placed a foreign ruler on the throne of England, introducing European rather than Scandinavian society onto the isolated island" in "the last successful invasion of England."
